Quest. 23, pp. 491-492. Hare is 100 hare-leaps ahead of a hound. Hare takes five leaps while the hound takes four, but three hound leaps equal four hare leaps.


Edward Cocker. Arithmetic. Op. cit. in 7.R. 1678. Chap. 10, quest. 32. 1678, p. 181; 1715: p. 121; 1787: p. 106. This problem is attributed to Moor's or More's Arith. cap. 8, qu. 7. 1678 states O-(40, 50), T = 3, giving answers 12 days and 600 miles. 1715 states O-(40, 50), T = 3, giving answers 32 days and 600 miles. 1787 states O-(48, 50), T = 3, giving answers 12 days and 600 miles. I am surprised at the misprints here.

Isaac Newton. Arithmetica Universalis, 1707. ??NYS. English version: Universal Arithmetic, translated by Mr. Ralphson, with revisions and additions by Mr. Cunn, Colin Maclaurin, James Maguire and Theaker Wilder; W. Johnston, London, 1769. (De Morgan, in Rara, 652 653, says there were Latin editions of 1722, 1732, 1761 and Raphson's English editions of 1720 and 1728, ??NYS.) Resolution of Arithmetical Questions, Problem V, pp. 180 184. Begins with MR(7/2, 8/3; 59) with second delayed by 1. Then "The same more generally" does O(c/f, d/g) with second having a headstart of distance e and either a headstart or delay of time h and MR(c/f, d/g; e) with second having either a headstart or delay of time h. Then does example: O(13, 1) with second starting distance 90 ahead, but first delayed by 3 days. Then repeats original example from general viewpoint.

Alexis-Claude Clairaut. Élémens d'algèbre. 1746. ??NYS -- cited by Tom Henley. Discusses the relation between overtaking and meeting problems and the use of negative rates or negative headstarts to make them algebraically the same.

Prob. 67, 1793: p. 70; 1799: p. 75 & Key p. 102. Hound & hare, O-(21, 15), D = 96. The actual rates are not given, only their ratio, so one can determine where the hare is caught, but not when.

Prob. 12, 1793: p. 78; 1799: p. 84 & Key p. 109. A and B start to circle a wood of circumference 135, starting at opposite sides and going in the same direction. A goes 11/2, B goes 17/3. When do they meet? O (11/2, 17/3), D = 67½.

Prob. 6, 1793: p. 189; 1799: p. 201 & Key p. 245. Hare starts 5 rods and 34 sec before a greyhound and goes at 12 mph, while the hound goes 20 mph. Using 320 rods to the mile, this is O-(16/15, 16/9) where the slower has a headstart of T = 34 and D = 5.
